[GISel] Erase the root instruction after emitting all its potential uses (#77494)
This tries to fix a bug by resolving a few FIXMEs. The bug is that `EraseInstAction` is emitted after emitting the _first_ `BuildMIAction`, which is too early because the erased instruction may still be used by subsequent `BuildMIAction`s (in particular, by `CopyRenderer`). An example of the bug (from `match-table-operand-types.td`): ``` def InstTest0 : GICombineRule< (defs root:$a), (match (G_MUL i32:$x, i32:$b, i32:$c), (G_MUL $a, i32:$b, i32:$x)), (apply (G_ADD i64:$tmp, $b, i32:$c), (G_ADD i8:$a, $b, i64:$tmp))>; GIR_EraseFromParent, /*InsnID*/0, GIR_BuildMI, /*InsnID*/1, /*Opcode*/GIMT_Encode2(TargetOpcode::G_ADD), GIR_Copy, /*NewInsnID*/1, /*OldInsnID*/0, /*OpIdx*/0, // a GIR_Copy, /*NewInsnID*/1, /*OldInsnID*/0, /*OpIdx*/1, // b GIR_AddSimpleTempRegister, /*InsnID*/1, /*TempRegID*/0, ``` Here, the root instruction is destroyed before copying its operands ('a' and 'b') to the new instruction. The solution is to emit `EraseInstAction` for the root instruction as the last action in the emission pipeline.
